My invention relates to a new and improved slat Venetian blind slats are usually made of wood? or some other relatively heavy materiaL-which requires painting and'finishing. andwhi'ch is relaother inexpensive material, but; due to the inherent nature of thematerial, there isa d'ecided tendency for them to sag or-otherwise'become dis:

torted, unless heavilyreinfor'ced, which, of course,

On the other hand, Venetian blind slats have been made of paper or fiber Befierririg'to medrmmei; I Briefly, I provide a lower portion or faoez ofg the. i of: pape'ror pthcr'irelatively :thimma Supertmpcmed this porti on;;I,p G an upper-face or portion iandioldt e ing edges-3' of the tsovertheedges the portion $2,, and ioldingglgshorten thebross section of the portion l to a less width thangthe portion 2-,,SO'Ea.tGIbOW.MIBiTGFalich flle portion- 2, as cleairlyappament the draswing,,Figures I: j

7 members together; Thuemembers may'be'isccured and arranged that itwill maintai-nits shape and appearance.

These and other objects of my invention, which apparent to one skilled in the art upon readin these specifications, I accomplish by that cer- .tain construction and arrangement of-parts of which I shall now describe an exemplary embodiment. Reference is now made to the drawing which forms a part thereof and in which:

Figure l'is a perspective view of a portion or section of my novel slat. l

' Figure 2 is an enlarged cross section of the edge portion of my slat, taken on the section line 2-2 of Figure 1. V

Figure 3 is a cross section of amodified'form of my novel slat.

Figure 4 Ba cross section of another modification of my novel slat, wherein the upper portion is of heavier material than the lower portion. Figure 5 is a modification of my novel slat,

twill be set forth hereinafter, or whichwill be wherein the edges are folded overto increase I rigidity of the slat.

Briefly in the practice of my invention I provide a Venetian blind slat formed of paper ,or

other relatively thin but stiff material and having an upper anda lower face. The Width or transverse section of the upper portion of my slat is greater than that of the lower portion, so

by crimping, riveting, gluing, or by any securing means well known in the art.

The resultingstructure, as is apparentin'Fige j ures: 1 and 2, consists of a. Venetian blind slat, wherein the cross section consists of a bowed or arched upper surface and a fiat'lowerisurface. I I

The lower surface I is kept under a stretching tension by the archi-ng of the upper portion 2.

The beading 4 on'the edge also assists inmaintaining the In Figure 3, I have shown a modification wherein the upper portion '2, besides being arched, has folders 6 formed therein. In'this modification the edges 3 of the lower portion 1 are directly folded over the edges of the upper portion 2; By this construction the formed paper slat is given a thickness which'makes it appear as if formed of 7 wood or other heavy material; It is to be noted that in this modification the lower portion l is constantly maintained under stretching tension by the arched upper member-Z.

The modification shown in Figure 4 is quite similar to that shown and described in-Figures 1 and 2, excepting that the upper portion 2 is of heavier material thanthe lower portion l', and thus the lower portion l is maintainedunder a greater stretching tensionthanwould otherwise It is also to be noted that in this modification, no-beading isprovided onthe edges, since the relatively heavy upper portion Zis sufiibe the case.

" ciently stifi to maintain a straight edge,

The modification illustrated in Figure 5. is

again similar to that in Figures 1 and 2, excepting that in this instance the upper and lower portions are of the same thickness and the edge of the upper portion is folded back upon'itself other alignment and configuration ofthe edge;

It is to be understood that my novel Venetian blind slat is combined together in the usual manner of forming Venetian blinds. The appearance of the finished blind is extremely pleasing to the eye and quite sturdy. .In some cases the material forming the slats may be slightly transluscent and thus present pleasing and varying effects due to the transmission of light therevthrough. f.

It is to be undersea that difierent iorms of my preferred form may be made without departing from the spirit of my invention. Having thus described y invention, what -I claim as new and desire to secureby Letters Patent is: i r

A slat for a Venetian blind'comprising a pair of members assembled together, one of said members of greater width than the other member forming a hollow arched .-s1at having .at-flat bottom or base.
